WALTER C. VASBINDER, OF PAWHUSKA, OKLAHOMA.

AUTOMATIC CHALKING-CUE.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed July 10, 1911. Serial No. 637,780.

To all whom it may concern.

Be it known that I, WALTER C. VAs- BINDER, a citizen of the UnitedStates, residing at Pawhuska, in the county of Osage and State ofOklahoma, have invented certain new and useful Improvements in AutomaticChalking-Cues; and I do hereby de clare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in automatic cuechalkers and more particularly to that class adapted to be attached to apool table or billiard table and my object is to provide a receptaclefor holding the chalk in position to receive the tip end of the cue.

A further object is to so arrange the receptacle in which the chalk .isplaced that saidchalk will move lengthwise of the receptacle when thetip end of the cue is pressed against the chalk.

A further object is to provide means for causing the chalk to rotatewhen moving lengthwise of the receptacle, and,

A. further object is to provide means for returning the chalk to itsinitial position when the pressure of the one is removed therefrom.

Other objects and advantages will be hereinafter set forth and pointedout in the specification.

In the accompanying drawings which are made a part of this application,Figure 1 is a side elevation of a pool table showing my improved deviceattached thereto. Fig. 2 is a central, longitudinal, sectional view ofthe chalking appliance as seen on line 2-2, Fig. 3, the chalk beingshown in its normal position. Fig. 3 is a sectional view as seen on line83, Fig. 2, showing the one in serted and the chalk forced toward the.rear of the housing. Fig. 4 is a rear end elevation of the chalkreceptacle, and, Fig. 5 is a front elevation thereof.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates the pooltable which is constructed in the usual or any preferred manner, to thebody of which is attached my improved chalking device which consists ofa housing 2, said housing being formed upon a base 3, which base issecured in any preferred manner to the outer face of the body of thepool table.

The interior of the housing 2 is preferably cylindrical in cross sectionand is of suflicient diameter to receive a block of chalk 4, said blockof chalk being introduced into the housing through a slot 5, which block4' is preferably located adjacent the forward end wall 6 of the housing.

In order to cause the block of chalk to rotate when it is being movedlengthwise of the housing, a shaft 7 is extended longitudinally of thehousing, said shaft having a spiral groove 8 which engages with a tongue9, carried by a cross bar 10 through which the shaft extends, theforward end of the shaft 7 being preferably provided with prongs 11which engage the chalk and cause the same to rotate with the shaft.

The rear end of the shaft 7 terminates in va stem 12, the free end ofwhich finds a bearturn the shaft 7 and the block of chalk to theirinitial forward positions when not in use. In applying the chalkingdevice to use, the tip end of the one 16 is entered through an opening17 in the end wall 6 and into engagement with the chalk 4:, when bydirecting pressure against the cue the chalk will be forced lengthwiseof the housing and caused to rotate by the action of the shaft 7 therebyproperly applying the chalk to the tip of the cue. As soon as thepressure on the one is released, the spring 15 will immediately returnthe chalk to the forward end of the housing.

As soon as the block of chalk has served its usefulness, it is removedthrough the slot 5 and a new block of chalk introduced in its place.

From this construction it will be readily seen that the chalk willalways be in position for use and the chalk will be more evenly andthoroughly applied to the tip of the cue. It will likewise be seen thatby rotating the chalk it will be more thoroughly applied to the tip andthe liability of twisting the tip from the one will be materiallylessened.

lVhat I claim is The one chalker comprising a base, a housing secured tosaid base and having openings in its end walls, a cross bar in saidhousing intermediate the ends thereof, a shaft mounted in said cross barand extending longitudinally of said housing, said shaft having a spiralgroove at one end and a reduced stem at the other end that engages oneof said openings and projects beyond said housing when pressure isapplied to said shaft, a laterally projecting tongue carried by saidcross bar engaging said spiral groove, prongs formed upon either side ofthe longitudinalcenter and at the forward end of the shaft for engaginga piece of chalk, and a spring engaging around said reduced stem betweenthe rear end wall of said housing and said shaft to cause the latter toreturn to its normal position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
